Thermal Management datasheet and documents for MAX6639ATE+

MAX6639ATE+

Thermal Management Overview

The MAX6639ATE+ is a 2-channel temperature monitor with dual automatic PWM fan-speed controllers. It operates from 3.0V to 3.6V and features an SMBus interface. The device monitors its own local temperature and up to two external diode-connected transistors, typically located on CPUs or GPUs. It provides ±1°C remote accuracy and measures temperatures up to +150°C. The unit includes two open-drain PWM outputs for fan drive, capable of being pulled up to +13.5V, and supports tachometer feedback for precise speed control.

Thermal Management Feature Summary

Dual thermal-diode inputs for monitoring external components
Automatic fan spin-up ensures reliable cooling system start
Controlled rate-of-change prevents unobtrusive fan-speed adjustments
Fail-safe protection initiates temperature monitoring immediately at power-on reset

Thermal Management Applications

Desktop Computers
Notebook Computers
Servers
Networking Equipment

Thermal Management Procurement Notes

Verify the specific suffix 'ATE+' corresponds to the 16-pin TQFN-EP package when sourcing replacements. Confirm that the component meets lead-free and RoHS compliance requirements as indicated by the '+' designation. Ensure the operating range matches the -40°C to +125°C specification for your application environment.

Thermal Management Selection Notes

Select this component for systems requiring integrated thermal management and active cooling control. It is suitable for applications needing precise remote temperature sensing via diode-connected transistors. The dual PWM outputs allow independent control of multiple fans. Verify compatibility with standard SMBus protocols for system integration.

Thermal Management Part Context

This part belongs to the MAX6639 family of hardware monitors. It is designed to replace older discrete thermal management solutions. The device integrates both sensing and actuation capabilities into a single chip, reducing board space and complexity compared to separate sensor and controller ICs.
